DRAW-IRON FOR HORSE-CARS.

SPECIFICATION forming part of Letters Patent No. 449,644, dated March 31, 1891. Application filed August '7, 1890. Serial No. 361,378. (No model.)

To all whom it may concern:

3e it known that I, JOHN M. BLONDELL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented 5 certain new and useful Improvements in Draw-Irons for Horse-Oars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to draw-irons for horsecars; and it consists of certain wood parts and combinations of parts, the separate features of which will be specifically pointed out in the claims concluding this specification.

The object of my invention is to provide for coupling the pole and the pole-rest to the draw-iron by one and the same coupling-pin, and thereby provide a more satisfactory coupling device and render the coupling and uncoupling easier and quicker than can be effected by a separate coupling-pin for the pole and a separate coupling-pin for the pole-rest, as hitherto proposed. In carrying out this 5 object the holes in the coupling-arms for the pole and the arm for the pole-rest must not only be coincident, but of equal size, and the coupling-pin long enough to engage the three arms.

3 Referring to the accompanying drawings,

Figure 1 represents in vertical section a drawiron, a draft-pole, and a pole-rest formed by the pole-coupling pin. Fig. 2 shows a top view of the same; and Fig. 3 is a front view of the draw-iron with the coupling-pin removed.

a is the platform of the car, and b is the draw-iron firmly bolted to the platform by means of a base-plate c and formed with the 4 upper eyed jaws d, to which the pole is secured by the coupling-pin 6. At the lower end this draw-iron has an arm or bracket f, provided with an eye coincident with the eyes in the upper jaws, down into which the coupling-pin is extended to form what I call a removable pole-rest, as I shall presently state. This construction of removable polerest also gives advantage of a coupling as well as a rest for the pole.

.50 g is the pole, and his a stay-brace to support the pole and hold it at a proper elevation,

and i j are the bolt and its guard for securing the whiffletree to the pole. This stay-brace may be of any suitable form and construction for supporting the pole by means of a supplemental coupling with the coupling-pin. This supplemental coupling I prefer to make of an arm k, which is secured to the staybrace and is provided with an eye and is arranged to extend over the upper side of the lower arm of the draw-iron, so that the coupling-pin will pass down through these lapping eyed arms, and thus the removable couplingpin itself is made to form the pole-rest, which,

so far as I know and can find, is anovel construction in a draft-pole-coupling iron. The advantages due to this construction and arrangement are that the continuous bolt-coupling makes the draw-iron stronger, prevents the snapping ofii" of the upper jaws by dis- 7o tributing the leverage of the coupling-pin upon the top jaws and upon the bottom arm of said iron and throughout the length of said iron, it prevents the outer end of the pole from flying upward or downward, and it prevents the snapping off of the eye end of the pole.

I claim as my improvement- I 1. The casting I), having the upper arms 01 (Z for the pole and the lower arm f for the polerest, the said several arms having coincident openings, in combination with a coupling-pin (2, having a length suflicient to engage the pole-arms cl cl and the pole-rest arm f, as shown and described whereby the said pin is made to engage the pole and the pole-rest.

2. A draw-iron having the upper arms 01 d for the pole and the lower arm f for the polerest and having coincident holes, in combination with a coupling-pin engaging the said pole-arms and the said pole-rest arm and a pole having an arm is engaging the lower end of said coupling-pin, as shown and described, whereby the same pin couples the-pole and its stay-braoe-coupling arm.

In testimony whereof I affix my signature in presence of two witnesses.
